Many government are seeing Bitcoin or cryptocurrency as a threat to their financial system and they think it should be regulated to solve the problem. Do you think they can regulate Bitcoin ?
I don't think that is the problem here, and there is no way the government will be able to regulate bitcoin by itself. Governments can only regulate the usage of these currencies by the people, they can ban cutrencies in their country, but they will never get to control the bitcoin itself. They should not problem themselves about it.
